[0002] Infusion rubber stoppers are a type of rubber product widely used in the medical field. They are mainly used to seal infusion bottles or infusion bags. Usually, the infusion environment is in hospitals with good sanitary conditions. However, in some accident sites or special environments, emergency infusion is required. The harsh environment can easily cause the rubber stopper to leak, indirectly leading to contamination of the internal drugs. Summary of the Invention

[0003] The purpose of the utility model is to provide a combined high-sealing rubber plug to solve the above problems in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a high-sealing rubber stopper, characterized in that it includes a rubber stopper body, a hemispherical installation cavity is provided in the rubber stopper body, a sealing member is provided in the installation cavity, the sealing member is a hemispherical structure, and a reverse-bent shrinkage opening is provided at the bottom of the seal, a plurality of symmetrically arranged hanging ears are provided at the end of the shrinkage opening, a guide portion is provided at the top of the seal, and a plurality of locking portions are evenly provided on the side wall of the installation cavity, a clamping portion for engaging the locking portion is provided on the guide portion, and the sealing member is made of flexible silicone material.

[0005] In the above-mentioned high-seal rubber stopper, a medicine taking hole is provided in the rubber stopper body.

[0006] In the above-mentioned high-seal rubber stopper, a covering portion is extended upwardly from the outer side of the rubber stopper body, and the rubber stopper body also has a plug opening portion, and a sealing ring is provided on the inner wall of the covering portion.

[0007] In the above-mentioned high-sealing rubber plug, a clamping groove is provided on the outer wall of the shrinkage opening, and a shrinking ring is provided on the clamping groove.

[0008] In the above-mentioned high-seal rubber stopper, a medicine taking indicator ring is provided on the rubber stopper body.

[0009] Compared with the existing technology, this high-sealing rubber plug squeezes and contracts the arc-shaped sealing part inward to make the contraction part in close contact with the management, thereby increasing the sealing performance. At the same time, the clamping part and the locking part can prevent the sealing failure caused by retraction. The hanging ear makes the rubber plug more convenient and labor-saving to use. At the same time, the hanging ear can hang objects, making it more convenient and practical during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 、 2 As shown in Figure 3, the high sealing rubber plug includes a rubber plug body 5, a hemispherical installation cavity 7 is provided in the rubber plug body 5, a sealing member 4 is provided in the installation cavity 7, the sealing member 4 is a hemispherical structure, and a reverse-bent shrinkage opening 9 is provided at the bottom of the sealing member 4, and a plurality of symmetrically arranged hanging ears 11 are provided at the end of the shrinkage opening 9, a guide portion 6 is provided at the top of the sealing member 4, and a plurality of locking portions 13 are evenly arranged on the side wall of the installation cavity 7, and a clamping portion 14 corresponding to the locking portion 13 is provided on the guide portion 6. The sealing member 4 is a flexible silicone rubber. The material, the shrinkage mouth is fixed and supported by the rubber plug body 5 when in use. When in use, the needle is first inserted to take the medicine. After completion, the seal 4 is moved down by pulling the ear 11 downward. The arc-shaped installation cavity 7 and the clamping part squeeze and shrink the shrinkage mouth 9 and conflict with the pipeline to prevent the leaked liquid from flowing out and prevent foreign matter from entering. The locking part 13 and the clamping part 14 bite each other to prevent the sealing effect from being weakened due to the retraction of the clamping part. The ear 11 can serve as a handle when in use, and can also hang an indicator sign when it is unblocked, which helps to provide information to the user.

[0016] Preferably, a medicine taking hole 8 is opened in the rubber stopper body 5, which avoids the difficulty of taking medicine due to the rubber stopper body 5 being too thick, and increases the moving stroke of the sealing member 4 to adapt to pipelines of different sizes.

[0017] Preferably, a covering portion 2 is extended upward from the outer side of the rubber stopper body 5 , and a plug mouth portion 3 is also provided on the rubber stopper body 5 . A sealing ring 1 is provided on the inner wall of the covering portion 2 .

[0018] Preferably, a clamping groove 12 is provided on the outer wall of the shrinkage opening 9 , and a shrinkage ring 15 is provided on the clamping groove 12 .

[0019] Preferably, a medicine taking indicator ring 10 is provided on the rubber stopper body 5 .

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0021] Although this document frequently uses terms such as sealing ring 1, covering portion 2, plug opening portion 3, sealing element 4, rubber plug body 5, guide portion 6, mounting cavity 7, medicine dispensing hole 8, shrink opening 9, medicine dispensing indicator ring 10, hanging ear 11, engaging groove 12, locking portion 13, engaging portion 14, and shrink ring 15, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
